    Article published on oceanic transform faults

    An article on the role of seawater infiltration for oceanic transform fault seismicity has been published in the latest issue of Nature Geoscience. Oceanic transform faults are a major category of plate-bounding faults that cross-cut the mid-ocean ridge system. This study by Arjun Kohli, Monica Wolfson-Schwehr, Cécile Prigent, and Jessica Warren incorporates seawater hydration into […]

  • Former lab member Suzanne Birner has published an open access paper titled “Melt addition to mid-ocean ridge peridotites increases spinel Cr# with no significant effect on recorded oxygen fugacity“. In this paper, we report geochemical data, petrographic observations, and oxygen fugacity estimates for Southwest Indian Ridge peridotites. We show that low to moderate degrees of […]

  • Suzanne Birner’s article on mantle oxygen fugacity is now published in Earth and Planetary Science Letters. In this contribution, we show a broad congruence in the oxygen fugacity recorded in basalts and in peridotites from the Southwest Indian Ridge. While the two proxies for fugacity are in overall agreement, peridotites also indicate local redox heterogeneity. […]

    Smaller is stronger for olivine

    Research by Katie Kumamoto, Jessica Warren, and colleagues on the strength of olivine has been published in Science Advances. Our research suggests that tectonic plates are weaker than previously thought due to a size effect in olivine, the most abundant mineral in the Earth’s mantle. The article is summarized by Karen Roberts in this UDaily […]
